The TRAC has adopted a measure called Existing Peak-Hour Ridership/Capacity, with the following rationale: transit ridership is heavily concentrated in the peak work commute periods, so traffic benefits occur when highway V/C ratio are measures; strong ridership in the peak hour equates to the most heavily congested hour for roads, and significant ridership in the peak hour will improve roadway congestions.

This measure captures the existing ridership divided by the capacity measures in seats available. projects provided new transit service where service did not previously exist, will receive no points for this factor. Instead, applications for new transit service will received double points for the Proposed Peak hour Capacity Increase.
